Greg Kroah-Hartman, responsabil cu \u00eentre\u021binerea ramurii stabile a nucleului Linux, a exprimat sprijin pentru dezvoltarea de noi componente ale nucleului \u00een limbajul Rust. Ca persoan\u0103 prin care trece toat\u0103 informa\u021bia despre erorile \u0219i vulnerabilit\u0103\u021bile nucleului Linux \u00een ultimii 15 ani, el afirm\u0103 c\u0103 majoritatea erorilor din nucleu sunt cauzate de particularit\u0103\u021bile neprev\u0103zute ale limbajului C, care sunt complet excluse \u00een codul scris \u00een Rust. <\/p>\n

Folosind Rust, probleme precum accesarea memoriei dup\u0103 eliberare, dep\u0103\u0219irea limitelor buffer-ului (par\u021bial), eliberarea incorect\u0103 a resurselor \u00een timpul gestion\u0103rii erorilor \u0219i verific\u0103rile uitate ale codurilor de eroare vor r\u0103m\u00e2ne \u00een trecut, permi\u021b\u00e2nd \u00eentre\u021bin\u0103torilor s\u0103 se concentreze asupra erorilor reale, precum st\u0103rile de concuren\u021b\u0103 \u0219i problemele de logic\u0103, \u00een loc s\u0103 se piard\u0103 \u00een detalii \u00een timpul revizuirilor. <\/p>\n

Codul vechi existent scris \u00een limbajul C nu va disp\u0103rea nic\u0103ieri, dar pentru noul cod \u0219i noile drivere, implementarea Rust va permite \u00eembun\u0103t\u0103\u021birea semnificativ\u0103 a calit\u0103\u021bii. Implementarea Rust va oferi, de asemenea, posibilitatea de a structura interfe\u021bele interna\u0219ionale de programare ale nucleului astfel \u00eenc\u00e2t erorile de utilizare a API-ului intern s\u0103 fie practically excluse \u2014 \u00een nucleu s-au acumulat prea multe API-uri complicate \u0219i confuze, care creeaz\u0103 o mare povar\u0103 pe umerii men\u021bin\u0103torilor \u00een munca lor de verificare a utiliz\u0103rii corecte a acestor API-uri. Pe parcursul dezvolt\u0103rii leg\u0103turilor Rust, men\u021bin\u0103torii au ocazia s\u0103 reg\u00e2ndeasc\u0103 \u0219i s\u0103 ordoneze API-ul, ceea ce va aduce beneficii tuturor, inclusiv celor care folosesc limbajul C. <\/p>\n

Greg nu consider\u0103 c\u0103 Rust este o \u201eglon\u021b argintiu\u201d care va rezolva toate problemele din nucleu, dar acest limbaj va ajuta cu siguran\u021b\u0103 \u00eentr-un num\u0103r uria\u0219 de situa\u021bii. Suportul pentru Rust va satisface, de asemenea, nevoia dezvoltatorilor de drivere care sper\u0103 s\u0103 ob\u021bin\u0103 un instrument care s\u0103 le permit\u0103 s\u0103 scrie cod pentru hardware-ul lor, evit\u00e2nd multe tipuri de erori. C\u00e2t despre amestecarea mai multor limbaje, Greg nu consider\u0103 c\u0103 este o problem\u0103 mare; \u00een opinia sa, \u00een trecut, dezvoltatorii nucleului s-au descurcat cu probleme mult mai serioase, iar nu exist\u0103 un motiv s\u0103 renun\u021b\u0103m la promovarea \u00een nucleu a unor idei noi \u0219i bune care vor ajuta la asigurarea succesului proiectului pentru urm\u0103torii 20+ ani. <\/p>\n

La discu\u021bie s-a al\u0103turat \u0219i Kees Cook, fost administrator principal de sistem la kernel.org \u0219i lider al echipei de securitate Ubuntu. Kees a subliniat c\u0103 nu este vorba despre rescrierea codului existent \u00een nucleu, ci despre oferirea posibilit\u0103\u021bii de a utiliza Rust pentru a crea noi drivere \u0219i subsisteme. Utilizarea Rust pentru codul nou va permite nu doar reducerea num\u0103rului de erori legate de gestionarea memoriei, ci \u0219i scurtarea timpului de dezvoltare. Viteza de dezvoltare cre\u0219te datorit\u0103 reducerii efortului de depanare \u0219i a garan\u021biilor stricte oferite de limbaj, care permit identificarea erorilor \u00eentr-o etap\u0103 timpurie a scrierii codului, chiar \u00eenainte de \u00eenceperea test\u0103rii produsului. <\/p>\n

Eficien\u021ba tacticii de utilizare a Rust pentru \u00eembun\u0103t\u0103\u021birea calit\u0103\u021bii codului nou a fost deja demonstrat\u0103 de Google pe platforma Android. S-a ar\u0103tat c\u0103 principala surs\u0103 a problemelor de securitate este codul nou, iar \u00eembun\u0103t\u0103\u021birii calit\u0103\u021bii acestuia ar trebui s\u0103 i se acorde o aten\u021bie deosebit\u0103. \u00cen cazul codului vechi, exist\u0103 o dependen\u021b\u0103 exponen\u021bial\u0103 a securit\u0103\u021bii de timp (de exemplu, codul de 5 ani, \u00een medie, are o densitate a vulnerabilit\u0103\u021bilor de 3,4 ori mai mic\u0103 dec\u00e2t codul nou).
